Filter by:In a prospective randomised study design to investigate, if a systematic risk factor screening for bleeding ulcer in patients, who following percutaneous coronary intervention (PCI) commence a one year combination treatment with low dose aspirin and clopidogrel, followed by prophylactic treatment with a proton pump inhibitor (PPI) in case of increased risk, can reduce the risk of bleeding ulcer. Based on the recently raised suspicion that PPI's, possibly except pantoprazole, reduce the effect of ADP-receptor inhibitors, pantoprazole has been chosen as prophylaxis in the screening group, and analyses will be done to ascertain whether PPI treatment increases the risk of coronary events. Further analyses will be made to see whether PPI prophylaxis in high risk patients can increase compliance with the antithrombotic treatment through a reduction of side effects, thereby reducing the risk of myocardial infarction in particular stent thrombosis. The study population will be analyzed further to identify the patients, who will benefit the most from PPI prophylaxis Hypothesis: screening heart patients for risk factors for bleeding ulcer and subsequently treating high risk patients with PPI can reduce the incidence of bleeding ulcer and increase compliance with the antithrombotic treatment; thereby possibly reducing the risk of coronary events and improving survival. Initial a description of the prevalence of risk factors will be done.
The purpose of this study is to confirm the safety profile / factors which impact safety and efficacy in patients given triple therapy for Helicobacter pylori eradication with Nexium + amoxicillin (AMPC) + clarithromycin (CAM), or Nexium + AMPC + metronidazole (MNZ) in usual post-marketing use.
The purpose of this study is to understand the immune response activated in the human gastrointestinal tract by Trichuris Suis Ova (TSO) in patients with ulcerative colitis.
SUMMARY Rationale: Buruli ulcer, caused by Mycobacterium ulcerans, is an ulcerative disease endemic in West Africa. It often leads to functional limitations. Treatment was by extensive surgery, until in 2005 gradually antibiotic treatment for eight weeks with rifampicin and streptomycin was added. Observation of Buruli ulcer lesions of limited size during antibiotic treatment showed that during treatment there is a paradoxical increase of the lesion, with a decrease of the lesion after week 14. Current WHO protocols advise to decide whether surgery is needed four weeks after the start of antibiotics. This might be too early in the healing process. The investigators hypothesize that delay in surgery is safe, and that it results in a reduction of the number of surgical interventions. Objectives: Primary Objective of this study is to compare the need for surgical treatment in standard timing of surgery at the end of eight weeks antimicrobial treatment with a policy to postpone surgical treatment until week 14. Secondary Objectives are to study whether postponing surgery leads to less extensive surgery and a change in frequency of functional limitations; Study design: Patients will be randomized for surgery at week 8 after start of antibiotic treatment and week 14 after start of treatment. Reasons for treating doctors to decide to intervene with surgery will be according to current clinical practice and will be clearly defined in this protocol. Standard care of eight weeks of rifampicin and streptomycin will be given. All patients will be followed and lesional size using acetate sheet recordings will be used during follow-up. Study population: Patients with a clinical picture of Buruli ulcer disease confirmed by diagnostic tests in the districts covered by the Buruli ulcer centers in Lalo and Allada, Benin. Patients who are pregnant, have a contraindication for general anaesthesia and children below three years old will be excluded. 130 Patients in each treatment arm will be included to detect a difference in percentage of patients needing surgery of 20 percent. Main study parameters/endpoints: Primary outcome measure is the number of patients healed without surgery. Secondary outcome measures are the extent of surgery by measurement of lesional size, functional limitations after the end of treatment and one year after the start of treatment and the duration of admission.
The purpose of this study is to determine if topical application of a hydrogel that contains plant extracts will improve healing of diabetic foot ulcers when compared to treatment with a hydrogel alone.
The purpose of this study is to compare the ability of Aquacel® Ag and Mepilex® Border Ag to manage bioburden in leg ulcers over a two week study period.
Chronic foot ulcers are particularly prevalent in patients with underlying diabetes mellitus. These ulcers are reported to be the leading cause of hospitalization among people with diabetes. The purpose of this study is to evaluate CureXcell® in treating chronic lower extremity ulcers in adults with diabetes mellitus. CureXcell® is a cell based therapy, containing activated homologous white blood cells prepared from donated healthy whole blood. A total of 280 patients will be randomized to receive either CureXcell® or sham.
To evaluate the effects of HPIPC for the treatment of symptoms of PAD
Ulcerative Colitis (UC) is a life-long incurable disease with remissions and exacerbations. Inflammation confined to the rectum occurs in a quarter of patients and can be extremely hard to treat. Many medications have been tried in order to control the inflammation, but they do not always work. One of the newer medications is the immunosuppressing medication, tacrolimus that has been shown to be effective in UC when taken orally. Unfortunately, the oral use of this medication can have numerous serious side effects. In order to overcome these side effects, the use of topical rectal tacrolimus has been examined. Pilot studies in ulcerative proctitis (inflammation confined to the rectum) resistant to conventional therapies have demonstrated a clinical remission in 75% of patients and although the medication was well absorbed through the lining of the bowel, the levels in the blood were very low and no serious side effects were reported. The findings suggest that this preparation is indeed effective for inflammation in the distal bowel and that the method of administration reduces side effects. Further work, however, now needs to be undertaken to validate the original findings.
The aim of this study is to assess the relationship between microscopic Geboes index of inflammation and clinical course of ulcerative colitis in patients treated with infliximab. The investigators propose to test the hypothesis if infliximab is able to induce histological remission and then change the clinical course of ulcerative colitis.
